GUS-QS8A-01-7502-JA Description

The GUS-QS8A-01-7502-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 75kΩ resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a 16-pin QSOP package, it offers a compact 4.9mm × 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained surface-mount (SMD) designs. The gull-wing termination ensures reliable solderability, while the 0.64mm terminal pitch facilitates high-density PCB layouts. With a maximum voltage rating of 100V and a total power rating of 0.75W (0.1W per resistor), this network balances efficiency and durability.
